Abstract This resource acts as a simple representation of the ISO 3166 definitions of country names. Usage Following is an example of a simple RDF document, using WAIL and this vocabulary, referencing the United Kingdom. <rdf:RDF xmlns:dc = " xmlns:rdf = " xmlns:wail = " ><rdf:Description><dc:title>Something</dc:title><wail:locatedIn><wail:Country rdf:about=" /></wail:locatedIn></rdf:Description></rdf:RDF> Note the URI pointing to the fragment of the schema that represents the United Kingdom.

Southampton ECS Web Team › The Modeller I’ve invented a new Batman villain. His name is “The Modeller” and his scheme is to model Gotham city entirely accurately in a way that is of no practical value to anybody. He has an OWL which sits on his shoulder which has the power to absorb huge amounts of time and energy. The Modeller In the first issue, “Batman vs the Modeller” the modeller gets away by confusing batman as to exactly which incarnation he currently is (Frank Miller, Golden age or Batman Begins) which forces Batman into an identity crisis where he registers different URIs and FOAF profiles for Batman and Bruce Wayne. Over the 3 issues there’s a running subplot about the modelers master weapon, the FRBR, which everyone knows is very very powerful but when the citizens of Gotham talk about it none of them can quite agree on exactly what it does. While unpopular with the fans, issue two, “Batman vs the Protégé“, will later be hailed as a Kafkaesque masterpiece. I’m interested to see if I get any outraged comments.

annotation-ontology - Project Hosting on Google Code Ciccarese P, Ocana M, Castro LJG, Das S, Clark, T. An Open Annotation Ontology for Science on Web 3.0. J Biomed Semantics 2011, 2(Suppl 2):S4 (17 May 2011) Please read this carefully: Specification is undergoing changes. The Annotation Ontology specification is currently used as input for the activities of the W3C Open Annotation Community Group that works towards a common, RDF-based, specification for annotating digital resources. The Group effort starts by working towards a reconciliation of two proposals that have emerged over the past two years: the Annotation Ontology and the Open Annotation Model. AO: Annotation Ontology The Annotation Ontology is a vocabulary for performing several types of annotation - comment, entities annotation (or semantic tags), textual annotation (classic tags), notes, examples, erratum... - on any kind of electronic document (text, images, audio, tables...) and document parts.

Semantic Copyright Introducing fise, the Open Source RESTful Semantic Engine, Nuxeo Developers Blog Edit: fise is now known as the Stanbol Enhancer component of the Apache Stanbol incubating project. As a member of the IKS european project Nuxeo contributes to the development of an Open Source software project named fise whose goal is to help bring new and trendy semantic features to CMS by giving developers a stack of reusable HTTP semantic services to build upon. As such concepts might be new to some readers, the first part of this blog post is presented as a Q&A. What is a Semantic Engine? A semantic engine is a software component that extracts the meaning of a electronic document to organize it as partially structured knowledge and not just as a piece of unstructured text content. Current semantic engines can typically: categorize documents (is this document written in English, Spanish, Chinese? During the last couple of years, many such engines have been made available through web-based API such as Open Calais, Zemanta and Evri just to name a few. How to use fise? The engines endpoint

s foaf stories | the web, the world, us, you and them Very raw, sometimes verbatim but doubtless flawed notes from Harry Wood‘s excellent talk at Open Data Institute in London. #odifridays Many thanks to Harry for a great talk and to ODI for putting together these lunchtime lectures. The ODI have also published slides and audio from the talk. “An introduction to OpenStreetMap, the UK born project to map the world as open data, and a look at how volunteer mappers helped with disaster response in the Philippines after Typhoon Haiyan, with Harry Wood . Harry is a developer at transportAPI.com, and is on the board of the Humanitarian OpenStreetMap Team.” Note: this is un-checked, very raw notes that I typed while listening. Typhoons …phillipines area hammered during typhoon season. [shows video clip] More than 6000 died. Q: who has edited OSM? Maps … GIS / vector data will always be a bit complex, but we try to dumb it down. But the maps are a important aspect of disaster response. OSM editing -> appear on map can take ~ 10 mins.

Microdata: HTML5’s Best-Kept Secret | Webmonkey | Wired.com Given the amount of industry noise about native video and scripted animations, you’d be forgiven if you had never heard of the new microdata specification included in HTML5. Similar to outside efforts like Microformats, HTML5′s microdata offers a way of extend HTML by adding custom vocabularies to your pages. The easiest way to understand it is to consider a common use case. Let’s say you want list details about a business on your page — the name, address, telephone number and so on. To do that you’ll need to use some vocabulary in addition to HTML, since there is no <business> tag. Using microdata, you can create your own custom name/value pairs to define a vocabulary that describes a business listing. When a search engine spider comes along, it will know that not only is your data a business listing, but it can discover the address, the phone number, or even the precise geo-coordinates if you want to include them. Given that HTML5 is still a draft at this point, why bother? Microdata

HTML5 Microdata: Why isn’t anyone talking about it? Written by Brian Cray on September 8th, 2010 Many big web design blogs are raving about HTML5, as they should be. But if you read many of them, [1, 2, 3], you'll be bombarded with an over-publicizing of header, article, footer, et. al tags, which reminds me of circa 2002 when we were all jumping onto the XHTML bandwagon. But 8 years later where'd XHTML get us? HTML5 on the other hand is bringing with it a ton of actually useful technologies, including much needed advances in HTML forms, native video support, and a vector API/canvas. But back to circa 2010/2002-wannabe. So my fellow web design bloggers: let's shift our focus to something that's a part of the HTML5 definition, changes the way we write tags, and has actual benefits: Microdata. A few web design blogs, including one of my favorites, NETTUTS, has covered Microdata briefly, and I want to add some more fuel to the conversation. What is HTML5 Microdata? Old schoolies may remember this little thing called the Semantic Web.
